Technology Leadership

Based on years of extensive development work, AST is using the Surface Mounted Fluidics technology as first in class for its unique space products.

Serial Production of Space Equipment

Serial Production of Space Equipment

AST’s products are designed to allow for high-volume production at low production cost per unit – always keeping product quality at spaceflight level.

Products Made in Europe

Products Made in Europe

With the production based in Germany and key-partners located closeby, AST is a true European provider of fluidic spacecraft solutions worldwide.

Cost Effective Serial Production

Our design for serial production is unique in space business and yields significant cost savings at larger quantities as required by LEO megaconstellations.

Welcome to AST

The Perfect Solution for Space Applications

AST is leader in high performant and miniaturized flow control components and units for space applications. Our devices use fluid SMD technology to reduce system size and mass and to allow series production. Key feature of fluid SMD is the significant reduced number of welds and a quality optimized manufacturing process. All remaining welding joints are done in fully automized electron beam welding machines, providing a maximum of quality at a minimum of cost.

High Quality Products

High Quality Products

AST's products comply with highest quality standards as for classical space applications like in ESA / NASA missions.

Reliable Components

Reliable Components

All components in AST's products have undergone fierce design qualification and are checked for compliance to high quality standards before integration.

AST's Mindset

The Mission

Our longterm mission is to develop products based on technologies that allow large scale serial production of space components at high quality level. With increasing number of units and streamlined processes, the cost of components and devices will be lowered by at least one order of magnitude. Fast development cycles and component spin-in from commercial application are key to keep the pace of NewSpace projects.

What We Offer

High Pressure Flow Control Units

High Pressure Flow Control Units

The AST high-pressure flow controller reduces high inlet pressures and provides correct massflows of propellant. This is best suited for a single-thruster propulsion system.

Low Pressure Flow Control Units

Low Pressure Flow Control Units

FCUs are used to adjust the propellant gas flow to an electric thruster over a wide mass-flow range and very dynamically. This solution allows for highest in-orbit operational flexibility.

Electronic Pressure Regulator

Electronic Pressure Regulator

The EPR reduces high-pressure input to selected low-pressure output levels. It provides operational flexibility e.g. when using cold-gas thrusters in electric propulsion systems.

Cold Gas Thrusters

Cold Gas Thrusters

The AST Cold Gas Thruster is a minuature thrust device with extensive ground testing and has flight heritage. The thrust level is about 50mN depending on media and pressures.

Fill- and Drain-Valve

Fill- and Drain-Valve

AST has developed a fill and drain valve that makes a perfect fit onto the Flow
Path Board of its pressure regulator (EPR) and high-pressure flow control unit.

Isolation Valve

Isolation Valve

AST's miniaturized low pressure valves can be used in complex fluidic systems as stand-alone valves. They have demonstrated a total of 1.1 billion (10^9 ) operational cycles.
